📌 How to design and implement core networking infrastructure on Azure?

Navigating the complexities of Azure's networking infrastructure requires a strategic approach, encompassing the technical aspects of configuration and considerations for security, cost management, scalability, and performance.

❶ IP Addressing and Network Segmentation in Azure

Effective IP management is the cornerstone of Azure's networking strategy, ensuring secure and efficient operations.
◆ Network Segmentation: Tailoring IP address spaces for different segments like production and development is crucial for enhancing security and traffic management. This involves defining clear boundaries and roles for each segment.
◆ VNets are instrumental in providing isolated network environments. Setting up VNets with specific address ranges is fundamental in creating secure, isolated operational spaces.
◆ Subnetting and Delegation: Optimizing network performance involves creating subnets for specific services (like gateways and firewalls) and delegating control within subnets for granular management.
◆ Public IP Management: Efficiently managing public IP addresses involves organizing them with prefixes and understanding when and how to use them, including the integration of external IP ranges for personalized addressing.

❷ Name Resolution and DNS Management

Robust DNS management within Azure is key to seamless domain name resolution and network integrity.
◆ Internal DNS Configuration: Setting up internal DNS within VNets ensures accurate domain name resolution, a fundamental aspect of network reliability.
◆ DNS Zone Management: Handling both public and private DNS zones is about balancing internet domain name resolution with internal network security and control.
◆ Azure DNS Private Resolver: Implementing this tool offers enhanced DNS resolution flexibility, catering to complex network setups.

❸ Connectivity and Routing in Azure

Efficient network connectivity and routing are pivotal for Azure's operational effectiveness.
◆ Service Chaining and VPNs: Planning network topologies for routing and access, including secure VPN connections, is essential for robust network architecture.
◆ VNet Peering and Network Management: Direct network access between VNets and centralized control over multiple VNets are crucial for streamlined operations.
◆ Custom Routing and Traffic Management: Implementing user-defined routes and managing traffic flow are key for tailored network performance.

❹ Network Monitoring

Maintaining network health and security is paramount in Azure's dynamic environment.
◆ Network Performance Insights: Tools like Azure Network Watcher provide essential insights into network performance and issues, enabling proactive management.
◆ Security Measures: Implementing DDoS protection and monitoring tools like Microsoft Defender for DNS are critical for safeguarding the network against emerging threats.
